Answer:
Temuchin eventually became known as Genghis Khan, or Universal Ruler.
Step-by-step explanation:
Genghis Khan, born with the name of Temujin, was a Mongolian warrior and conqueror who unified the nomadic tribes of this ethnic group of northern Asia, founding the first Mongol Empire, the largest contiguous empire in history.
In 1206, Temujin was chosen lord of all the nomads of the steppe and received the title of Genghis Khan, which means "universal ruler".
Under his leadership as Great Khan, the Mongols began a wave of conquests that extended their dominion to a vast territory, from Eastern Europe to the Pacific Ocean, and from Siberia to Mesopotamia, India and Indochina.
